The article of the present design relates to a heat sink for an electronic component and other sources are operating at excessively high temperatures in open/closed area in automotive industry, such as a Head-up Display (HUD) for a vehicle. The HUD has a light source to project an image or graphics on a windshield of the vehicle. The heat sink includes a bottom plate and a plurality of fins arranged parallel to the vehicle moving direction on the bottom plate. It will extract more heat at the time of acceleration and deceleration of the vehicle. The bottom plate is configured to be attached to the light source and prevent the light source from operating at excessively high temperatures. The typical fin structure gains the surface area and improves the efficiency of heat exchange. 

CLAIM The ornamental design for a heat sink, as shown and described.
